Audi A8 L 6.0 quattro sedan with a 450-hp W-12 engine went on sale in late 2004 and is now named the A8 L W12. Audi's 335-horsepower, 4.2-liter V-8 includes five valves per cylinder. An adaptive four-setting air-spring suspension features continuous shock-absorber damping control, and it also permits speed-dependent lowering of the body for increased directional stability. Permanent quattro all-wheel drive is standard.
The A8 L rides on a 121-inch wheelbase, which is 5.1 inches more than the base A8. The low front end features a short overhang, and the back has a high tail. A high belt line that rises toward the rear highlights the A8's sporty appearance. The A8 L's rear doors are 5 inches longer than those on the shorter-wheelbase version for easy entry and exit. For 2006, five-spoke alloy wheels hold standard 18-inch tires, but 19-inch tires are available in the Sport package.
Five people fit inside the A8 and A8 L. The driver faces a multifunction four-spoke steering wheel and uses an electromechanical parking brake. Fine wood trim extends to the sides of the interior and complement Valcona leather upholstery. Power front seats can be equipped with massage, heating and ventilating functions. The premium Bose surround sound system includes a CD changer and 12 speakers. Audi Exclusive packages for 2006 A8 models include contrasting black piping and unique wood trim.
Audi's 4.2-liter V-8 produces 335 hp and drives a six-speed-automatic transmission that permits Tiptronic manual gear selection and a Dynamic Shift Program that reduces the number of gear changes needed. All A8s have quattro all-wheel drive.
